What Color Light Do Plants Grow Best In

While there has been some debate recently on the merits of green light during a plant s growth cycle there s a good reason plants normally have green leaves that s because they are least effective at absorbing this type of light.

Plants are genetically programmed to grow using sun light which we consider to be white light or yellowish white light. The ideal ratio is somewhere around 5 1 red to blue. This light looks white because it contains all of the colors of a rainbow and when these colors are all mixed together they look white. Yield results left to right.

So what colour light do plants grow best in. In general plants use less of the green light they absorb than any other part of the spectrum and that s why your plants appear green but that doesn t mean they don t use any green light at all during the photosynthesis process.
